Ii-VLAN ezimileyo zikwabizwa ngokuba zii-VLAN ezisekwe kwizibuko.Oku kukuchaza ukuba leliphi izibuko leliphi i-VLAN ID.Ukusuka kwinqanaba lomzimba, ungacacisa ngokuthe ngqo ukuba i-LAN efakiweyo ihambelana ngqo nezibuko.
Xa umlawuli weVLAN eqala ukuqwalasela ubudlelwane obuhambelanayo phakathi kwe-port yokutshintsha kunye ne-ID ye-VLAN, ubudlelwane obuhambelanayo bulungisiwe.Oko kukuthi, i-ID yeVLAN enye ehambelanayo inokumiselwa ukufikelela kwizibuko kwaye ayinakutshintshwa kamva ngaphandle kokuba umlawuli uqwalasela kwakhona.
Xa isixhobo sidityanisiwe kweli zibuko, ungafumanisa njani ukuba iVLAN ID yenginginya iyahambelana nezibuko?Oku kumiselwe ngokoqwalaselo lwe-IP.Siyazi ukuba i-VLAN nganye inenombolo ye-subnet kwaye yeyiphi izibuko ehambelana nayo.Ukuba idilesi ye-IP efunwa sisixhobo ayifani nenombolo ye-subnet ye-VLAN ehambelana ne-port, uxhulumaniso aluphumeleli, kwaye isixhobo asiyi kukwazi ukunxibelelana ngokuqhelekileyo.Ngoko ke, ngaphezu kokudibanisa kwi-port echanekileyo, ifowuni kufuneka inikwe idilesi ye-IP yecandelo lenethiwekhi ye-VLAN, ukuze ifakwe kwi-VLAN.Ukuze uqonde oku, kuyimfuneko ukuqonda ukuba i-subnet iqukethe i-IP kunye ne-subnet mask.Ngokubanzi, kuphela amasuntswana amathathu okugqibela esubnet asetyenziselwa ukuqondwa kwegama lokugqibela.
.
Ukushwankathela, kufuneka siqwalasele iVLAN kunye nezibuko nganye nganye.Nangona kunjalo, ukuba ngaphezu kwekhulu lezibuko kwinethiwekhi kufuneka ziqwalaselwe, umsebenzi obangelwayo awukwazi ukugqitywa ngexesha elifutshane.Kwaye xa i-ID ye-VLAN idinga ukutshintshwa, kufuneka ihlaziywe-oku ngokucacileyo akufanelekanga kwezo intanethi ezifuna ukutshintsha i-topology structure rhoqo.
Ukuze kusonjululwe ezi ngxaki, ingqikelelo yeVLAN eguqukayo iye yaziswa.Yintoni iVLAN eguqukayo?Makhe sihlolisise.
2. I-Dynamic VLAN: I-Dynamic VLAN inokutshintsha i-VLAN ye-port nangaliphi na ixesha ngokwekhompyuter eqhagamshelwe kwizibuko ngalinye.Oku kunokunqanda le misebenzi ingentla, njengokutshintsha useto.IiVLAN ezinamandla zinokwahlulwa ngokweendidi ezintathu:
(1) I-VLAN enedilesi ye-MAC
I-VLAN esekwe kwidilesi ye-MAC imisela ubunini bezibuko ngokubuza kunye nokurekhoda idilesi ye-MAC yekhadi lomnatha wekhompyutha eqhagamshelwe kwizibuko.Masithi idilesi ye-MAC "B" imiselwe njengeye-VLAN 10 ngokutshintsha, ngoko kungakhathaliseki ukuba yiyiphi izibuko ikhompyutha enedilesi ye-MAC "A" iqhagamshelwe kuyo, i-port iya kwahlulwa ibe yi-VLAN 10. Xa ikhomputha iqhagamshelwe kuyo izibuko 1, izibuko 1 yeyeVLAN 10;xa ikhomputha iqhagamshelwe kwizibuko 2, izibuko 2 yeyeVLAN 10. Inkqubo yokuchonga ijonga kuphela kwidilesi yeMAC, hayi izibuko.Izibuko liya kwahlulwa libe yiVLAN ehambelanayo njengoko idilesi ye-MAC itshintsha.
.
Nangona kunjalo, kwi-VLAN esekelwe kwidilesi ye-MAC, iidilesi ze-MAC zazo zonke iikhomputha ezixhunyiwe kufuneka ziphandwe kwaye zingene ngexesha lokumisela.Kwaye ukuba ikhomputha itshintshisa ikhadi lomnatha, usadinga ukutshintsha isethingi kuba idilesi ye-MAC ihambelana nekhadi lomnatha, elilingana ne-ID ye-hardware yekhadi lomnatha.
(2) I-VLAN esekelwe kwi-IP
I-subnet esekwe kwi-VLAN imisela i-VLAN yezibuko ngedilesi ye-IP yekhompyutha edityanisiweyo.Ngokungafaniyo ne-VLAN esekelwe kwidilesi ye-MAC, nokuba idilesi ye-MAC yekhompyutheni iyatshintsha ngenxa yokutshintshiselana kwamakhadi womnatha okanye ngenxa yezinye izizathu, nje ukuba idilesi ye-IP ihleli ingatshintshi, ingakwazi ukujoyina i-VLAN yokuqala.
Ke ngoko, xa kuthelekiswa neVLANs esekwe kwiidilesi zeMAC, kulula ukutshintsha ubume benethiwekhi.Idilesi ye-IP ingcaciso yoluhlu lwesithathu kwimodeli yesalathiso ye-OSI, ngoko sinokuqonda ukuba i-VLAN esekelwe kwi-subnet yindlela yokuseta amakhonkco okufikelela kwinqanaba lesithathu le-OSI.
(3) I-VLAN esekelwe kubasebenzisi
.
I-VLAN esekwe kumsebenzisi imisela ukuba yeyiphi i-VLAN yezibuko ngokutsho komsebenzisi wokungena wangoku kwikhompyuter eqhagamshelwe kwizibuko ngalinye lokutshintsha.Ulwazi lokuchonga lomsebenzisi apha luqhelekile ukuba ngumsebenzisi ongene ngesixokelelwano sekhompyuter, esifana negama lomsebenzisi elisetyenziswa kwindawo kaWindows.Iinkcukacha zegama lomsebenzisi zezolwazi olungentla koluhlu lwesine lwe-OSI.
